Abstract

Construction activities for water pipeline projects in industrial facilities present various occupational and operational hazards that may disrupt project performance if not properly controlled. This study aims to analyze the occupational risks associated with the water pipeline construction project of PT CATL Karawang using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. The research was conducted through field observation, work breakdown structure analysis, and semi quantitative risk assessment based on likelihood and severity scoring. The results indicated ten (10) dominant hazards across five (5) major activities including trench excavation, pipe lowering, pipe joint installation, backfilling and compaction, pressure testing, and site restoration. Three (3) risks were categorized as high level, namely trench collapse, pipe dropping during lifting, and stuck by heavy equipment, while the remaining risks were classified as medium level. Appropriate risk controls are recommended following the hierarchy of control, emphasizing engineering controls, administrative procedures, and mandatory use of personal protective equipment. The study concludes that the overall risk category of the project is moderate, high and requires consistent monitoring and implementation of control measures to reduce the probability of incident and ensure safe and continuous project execution.

Abstract

This study analyzes power losses due to load imbalance and the calculation of losses in distribution transformers at the Merauke City Customer Service Unit (ULP). The results show that most distribution transformers on the Angkasa, Bampel, Parako, Kompi, and Ermasu feeders experienced load imbalances exceeding the 20% tolerance limit according to SPLN D3.002-1:2014 standards, contributing to increased neutral currents and power losses, particularly in transformers with heavy loads and uneven phase distribution. After phase current balancing using ETAB 19, significant reductions in neutral current and losses were observed, with transformer efficiency increasing by an average of 2-5% per unit. A feeder-based, data-driven balancing strategy, involving the redistribution of load from dominant phases to deficit phases along with regular monitoring, proved effective in improving distribution system efficiency, extending transformer lifespan, and enhancing voltage quality for customers. These findings provide an operational basis for PLN ULP Merauke to prioritize distribution network improvements, maintain a minimum bus voltage profile of 93–95%, and reduce operational costs through regular load balancing.
